This is a modified subset of the Linux kernel sources. Linux was written by Linus Torvalds and others. This package was put together by AMD, in part from sources retrieved from the upstream linux git.

All files located in /usr/src/*/firmware are subject to a firmware license, which can be found in '/usr/share/doc/amdgpu-dkms-firmware/LICENSE'. Linux is copyrighted by Linus Torvalds and others.
